One example would be “DEPRECATION: Using the context switching form of {{each}} is deprecated. Please use the keyword form ({{#each items as |item|}}) instead.”. Clicking through the stack trace I cannot find any recognizable code. Shouldn’t the stack trace direct me to the template where the offending statement is?

I am also having this sort of trouble. In your case, you have no each helpers iterating for you in your templates? They’ve changed the syntax a few times. That’s the only depreciation warning that actually made sense to me.
